Originally we specified the Cdecl calling convention only for callbacks. After 2.12 we added the attribute also for all DllImports.
The default StdCall works just fine when calling native code via DllImports with the exception that it produces a memory leak since the caller(Gtk#) is expected to free the stack, which it does not do because .net assumes StdCall and therefore that Gtk+ will clean the stack.
We used a regular expression to add the Cdecl attribute back then, so either the RegEx was wrong and did not catch all the dll imports or the import has been added afterwards and the Cdecl attribute has simply been forgotten.

Could you please file a bug report (www.mono-project.com/Bugs) for this? Of course, we would also very much appreciate a patch as we are somewhat short-handed and it is unlikely that we will have the time to fix this soon :-).
